EXGAVATING-MACHINE.

To all whom it mag concern:

Be it known that I, FRANCIS DoNALnsoN, a citizenof the United States, residing at Yonkers, in the county of Westchester and State of N ew York, have invented certain new and ,useful Improvements in Excavating- Machines, of which the following is a specification. U My invention relates broadly to excavating machines, and more specifically to a type of excavating machine which is carried upon a wagon or railway truck.

The principal object of my invention is an excavating machine constructed in such manner that the excavating scoop is provided with an attached chute which is mountedcontrolled by a single movement, whichmovement both loads and empties the scoop.

Other and further objects of my invention will in partbe obvious and will in part be pointed'out in the specification hereinafter following, and the scope of the invention a will be indicated by the'appended claims.

Throughout the several figures of the drawings, like characters are used to represent like parts.

Figure l i, a View in side elevation of an excavating mechanism embodying the features of the invention. Fig. 2 is a top plan view thereof. Fig. 3 is an enlarged detail fragmentary View of the chute guide and actuating pinion. Fig. 4 is a view siniilar to Fig. 1, illustrating a modified embodiment.

Referringto the drawings by numerals, 1 indicates a supporting frame provided with wheel pedestals 2,and wheels 3, which wheels are mounted to travel upon track 4. An A frame 5 is fixed to and upstands from frame 1. The A frame is engaged at its upper end by stay 6 anchored to the rear end of the frame 1. A crane 7 is pivotally sup- 4 ported by the upper end of the frame 5 and comprises a pair of horizontal members 7 fixed at their rear end to a hollow ournal 8,

the front end of the member 7 being en- I gaged by inclined supporting beams 7 wh ch beams are spread apart just beneath their engagement with the members 7 and extend downwardly and are fixed to a cross v membert) of a turntable 10. The turn table 10 is rotatably mounted preferably upon' suitable roller bearings sustained in an annular journal guide'll fixed to the frame 1. The turn table 10 consists, as clearly shown in Fig. 2, formed integral therewith and leaving front and rear open spaces communicating with an turn table 10 is the bed plate of a'snitable annular discharge hopper 12. Fixed to-the of a ring with the cross member 9.

engine 13 geared to drive a gear wheel 14 I fixed to shaft 15. The shaft 15 is jonrnaled in suitable bearings fixed to standards 16 depending from the supporting beams 7 and connected at their lower ends toa subframe 15, fixed to the turn table 10. The

shaft 15 extends loosely through a pairv of 3 suitable guide plates 17-.v A pinion .18 is fixed to the shaft 15, between the guide plates 17, and is arranged to mesh with a rack 19 fixedto and extending longitudi-- 'nally ofthe bottom of a chute 20, which chute serves as a beam for the ordinary scoop or shovel 21 which is fixed to the end thereof. Each guide plate 17 is formed with a longitudinal guiding groove 1.7--'and-.the

rack 19 is formed with lateral flanges 17 projecting into the grooves 17 and serving through the hollow journal 8, under a pulley 26 journaled in brackets fixed to the framev 5, down to the winding drum 27. The drum 27 is adapted to be actuated by a gearing driven by a suitable engine, as 28. The en-' gine, gearing, and drum are sustained by a bed plate 29 mounted on the frame 1..

Cables 3030 are fixed to turn table 10 at.

opposite sides thereof as at 30' and extend about the turn table preferably in a groove 10 to and about rearwardly disposed guidi'ng pulleys 31 journaled on the frame 1, and thence to an actuating drum 32. The drum 32 is driven by an engine 33 through bed plate 29.

operating an ordinary dredging scoop by being first lowered and then thrust forwardly. When the scoop is loading, the engine 28 is .operated, taking up the cable 22Fand elevating the scoop to the position indicated in dotted lines in Fig. 1, the chute 20 swinging about shaft 15 as a pivot, As the scoop moves upwardly, the gear 14 is actuated by the engine 13 for driving the rack; 19 for effecting the requisite longitudinail inovement of the chute 2 0 so as to insure its assumption of the desired elevated position. Then the chute and scoop are thus elevated, the load will be delivered by gravity fromthe scoop down the chute and into the hopper 12. An upstanding shield 34 is.

fixed to turn table 10 and extends about and on each side of the beams 7'i i1 position for directing the discharge from the chute into the hopper. Preferably for convenience in manipulation, a car 35 mounted on a track of narrower gage and between the railseof the track upon which the wheels 3 are mounted so that said car may be moved freely beneath frame 1 to and from a position immediately beneath the chute hopper 12, whereby the load from the scoop 21 may be delivered directly along the chute 20,

through the turn table 10, and the hopper chute 12 into the car 35. The hopper 12 may obviously be connected to turn table 10 in any desired manner, but for convenience is illustrated as an integralpart therewith;

In the construction illustrated in Fig. 4, all enginery is removed from the frame 1' and is mounted on the turn table, and the structural re-arrangement for attaining this positionin of the enginery marks the sole difference etween this embodiment and that just described. Frame 1 carries the hopper chute 12 extending downwardly from turn table 10*. A mutilated gear 30 is fixed to frame 1 coaxially with turn .table 1O and meshes with a driving pinion 31 carried by a vertical drive shaft 82 and geared to be driven by engine 33. Engine 33 is mounted on a framing 4L0 whlch extends rearwardly from and in effect forms part of the turn table 10". The shaft 32 is journaled in framing 10 so as to cause the framing and connected parts to swing when the pinion 31 is driven and walks along the gear 30 The A frame 5 is fixed to the framing 4:0 in front of the turn table and the upper end is engaged by guys 6 fixed to framing 40 adjacent the rear end thereof. Engine 28 is mounted on framing 40 and is disposed.

for driving a drum 27 which engages cable 22 for manipulating. the scoop 21 The cable 22 extends forwardly and upwardly from the drum and is passed, over a pulley 2 1 journaled in the upper'end of a frame 5*. Chute 20 is identical with the chute 20 and extends between the legs of the A frame 5*. An engine 13 is sustained by framing 40 and is geared for operating the scoop and connected parts in the same manner as has been previously described.
